Hi, I would like to share with you small modification to your Bosch tool 12V and 18V chargers.
You can use it for almost all Bosch chargers what I have seen, for example part numbers GAL 18V-20, GAL 18V-40, GAL 1880, GAL 18V-160, AL 1820, AL1115CV, AL1130CV.
Bosch (today also other brands using the same system like Wurth, Fein) does not care if you destroy your batteries, because they can sell you new ones. So the marketing is telling you only about speed of the charging, so you will not wait for your batteries to charge too long. Me as a customer want the tools and batteries...
